Long story short: is a template engine changing documents on static webpages, that you can then host anywyere, because you don't need databases or server that has PHP or Python. Jekyll markdown HTML Usual Process Normally the process of adding new post looks like this: I write markdown document with setting parameters like title, date and tags when I’m happy with what I wrote (never), I commit changes and push it to repository on GitHub. Repository name comes from my nick and is also address for blog asvid.github.io Github after pushing to branch master builds website from sources using Jekyll - probably something like running jekyll build result of Jekyll build is not present in a repository, but you see it right now after visiting bloga page The above process works entirely automatically, no need of configuration on repo site or GitHub itself. All you need is having repo name that follows this pattern: . Normally it works. But... {user_name}.github.io I want plugins Sometimes you want to add something cool to your page. I wanted to have it in multiple languages, like Polish and English. Jekyll is not supporting this natively… but it is not impossible 😄 So I’ve found a plugin , that allows adding many languages on same page without need of complete rebuild or restructure. I used it, after a while it was kinda working. After a while longer it was working as I wanted. . Polyglot Locally After pushing changes to GitHub page wasn’t working properly. I learned that GitHub is not simply building everything you throw at it, but it has a of supported plugins. Polyglot is sadly not on this list, despite its creator's attempts to get it on the list. Whitelist itself is understandable for security reasons, we don’t want to GitHub go down because of some evil plugin or hidden bitcoin miner running on GitHub servers. whitelist But I really need this plugin Like every problem this one also has a solution. Even few of them. You can build the page locally and push it to the branch, and keep source on other branch like . There is also , that publishes NodeJS apps as GitHub Pages. master develop NodeJS package But I’m lazy and I don’t want to build manually and push sources and build result separately, also I don’t have NodeJS app, so I use solution number 3. GitHub Actions is a basic CI available for free for every repository. To use this CI you need to create Workflow with yaml configuration telling it what and when should happen. There are , and if  something is missing, you can do one yourself or combine few into one workflow. To add workflow go to your . GitHub Actions many available actions repository->actions->New workflow and then click link to set up a workflow yourself. This will add yaml file with config inside repository in directory .github/workflows To publish Jekyll blog with not whitelisted plugins I used configured inside workflow like this: Jekyll-Actions name: GitHub Pages publication on: push jobs: jekyll: runs-on: ubuntu-16.04 steps: - uses: actions/checkout@v2 # Use GitHub Actions' cache to shorten build times and decrease load on servers - uses: actions/cache@v1 with: path: vendor/bundle key: $-gems-$ restore-keys: |
          $-gems-
    # Standard usage - uses: helaili/jekyll-action@2.0.3 env: JEKYLL_PAT: $ # Specify the Jekyll source location as a parameter - uses: helaili/jekyll-action@2.0.3 env: JEKYLL_PAT: $ This action runs inside container, and then: ubuntu-16.04 downloads repository after each push (on every branch which is causing some issue) is using cache to not download same each run Gems runs action to build page and publish ot on branch , with a push that is possible thanks to master secrets.JEKYLL_PAT And this publishing on branch master means that you shouldn't push source changes to this branch. If you want to use this action, you need to push changes to develop and leave master only for files build and pushed by the script. How to create secret.JEKYLL_PAT Action itself works in isolated container and has no write access to your repository. It can read it because its public. To allow this, you need to create access token with public_repo scope, and then add it in repository as a secret with name expected by configuration . secret.JEKYLL_PAT You generate token from GitHub account settings: . After clicking on Generate new token fill the name and select checkbox public_repo. Settings->Developer Settings->Personal Access Tokens After clicking button on the bottom Generate token you will have the only chance to copy it, I suggest taking it 😃 Copied token needs to be pasted to repository secrets: . Name like in config and value is copied token. Settings->Secrets->New secret secrets.JEKYLL_PAT And it should work. At least works for me 😏 This article was also posted on Jekyll blog hosted on GitHub, with the use of free . Github Pages Previously published at https://asvid.github.io/github-page-deployment
